       Procedural style

SYNOPSIS

       bool maxdb_ping (resource  $link)

DESCRIPTION

       Object oriented style
       bool maxdb::ping (void  )

	Checks	whether  the  connection  to the server is working. If it has gone down, and global option maxdb.reconnect is enabled an automatic

       nect if necessary.

RETURN VALUES

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      /* check if server is alive */
	      if ($maxdb->ping()) {
		 printf ("Our connection is ok!
");
	      } else {
		 printf ("Error: %s
", $maxdb->error);
	      }

	      /* close connection */
	      $maxdb->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

	      /* check connection */
	      if (maxdb_connect_errno()) {
		 printf("Connect failed: %s
", maxdb_connect_error());
		 exit();
	      }

	      /* check if server is alive */
	      if (maxdb_ping($link)) {
		 printf ("Our connection is ok!
");
	      } else {
		 printf ("Error: %s
", maxdb_error($link));
	      }

	      /* close connection */
	      maxdb_close($link);
	      ?>

       The above example will output something similar to:

       Our connection is ok!
